PORTABLE CONCRETE ASH PIT.

Application filed May 14,

This invention relates to ashpits, and especially to portable ashpitsmade of concrete.

The chief object of this invention is to provide an ashpit that can bereadily knocked down and transferred from one place to another.

Other objects and advantages of this invention will be disclosed in thespecification, claim and drawings, in which:

Fig. 1 is a side elevation partly broken away.

Fig. 2 is a plan View partly broken away;

Fig. 3 is a View of a holder embedded in concrete.

Fig. 4 is a perspective view of a holder.

In some cities ordinances have been passed requiring ashes fromhousehold furnaces to be deposited in a suitable receptacle near analley way from which they may be readily removed. These ordinancesusually require that the ashpit be made of fireproof material, and inorder to prevent the necessity of frequent removal of the ashes from thepit, they are usually constructed of relatively large size, and when soconstructed as a single unit, the forms must be built on the premiseswhere the pit is to be located, and

it is to avoid this extra expense that I have devised an ashpitconstructed of several members which may be entirely fabricated in afactory and then removed to the premises Where the pit is to be locatedand there quick ly assembled.

The preferred method of construction of this invention consists of aplurality of rectangular slabs 1 of uniform size and shape of which thesides of the pit are constructed, provided on their upper sides withholes 2 adapted to engage dowel pins 3 embedded in the lower portion ofthe slab, as shown. at 4, While the concrete is in a plastic state. Itwill be noted that the dowel pins project from the underside of thebottom slabs and are inserted in the earth.

The end walls 5 are provided with holes 1928. Serial No. 277,604.

and dowel pins the same as the side slabs, but differ from the sideslabs in that each end of the end wall slabs are turned at rightanglesto hold the side slabs against lateral movement.

A metal, holder 6, shown in detail, in Fig.

4, preferably made of sheet metal, is of a curvilinear outline 1ncross-section.

The side members 7 lie in a straight line in the same plane, the centralportion being curved outwardly and upwardly providing an open space 8 inwhich the head 9 of a bolt 10 is adapted to enter when passed throughthe slotted opening 11.

he body of the bolt drops into the slot 12 when the dowel pins are inplace in the openings 2, thus effectively locking the side slabs to theend Walls. The holder 6 is placed in position while the concrete is in aplastic state, as is likewise the bolt 10, so that when the concretesets the slabs and end walls are ready to be assembled.

Having fully described my invention,-what I claim as new and useful anddesire to secure by Letters Patent is:

A portable ashpit of the class described, comprising a plurality ofconcrete sideslabs of identical shape and size, metal dowel pinsembedded in one side of said slabs adapted to fit in dowel pin holes inthe opposite side of the next mating slab, metal bolts having suitableheads embedded in each end of said to their major axes, metal holdersembedded 1n said quadrilateral members ad acent their ends adapted to beengaged by the protruding ends of said bolts.

In witness whereof I have hereunto afiixed my signature this 5th day ofMay, 1928.
